R6 ii e shutter read out speed?

Is there any reviews that tested this?

No test yet, but here's some other cameras  readoutspeed.

So where does R6II fit in..... probably in the R5 region

Is there a source for this graphic?

How is r5 is faster than r6 with more megapixels?

R6 has an older sensor inherited from 1 DX

In that case, if it inherited the r5 readout architecture it should be faster than the r5 because it has less lines.

I don't know the read-out speed of the different cameras, except I remember R5 being unusual fast for a non-stacked sensor. So I don't know if this graph is nonsense or not.

I just want to remind that many sensors has multiple modes (power-use and heating varies probably with them), so readout speed can be different in different cameras even though they use the same sensor. And most importantly, as far as I know the readout speed is usually different in photo- and video-modes. The graph doesn't tell if the numbers are from photo- or video-modes (I haven't watched the video mentioned as source).

The graph is nonsense.

The Sony A7R IV (and A7R V can be assumed the same with the same rebadged sensor) have readout speeds of 100 ms, making them the worst of all.

The Sony A7III and IV have readout speeds of 66 ms, placing them also on the poorest performing end, far behind a R7.

I can't say if Sony's values are with  14 or12 bit raw.

This can be your answer why Sony's value in this graph is not like  Jim Kassons 14bit test.

In this graph it says 1/16s  for R4

1/37s on A74 probably 12bit

All canons is 12 bit

Well it is the the way Canon make their linup and allways has.

The 6 serie is lower than the 5 serie

The 5 serie is lower than 3 serie.

But we'll see what the new R6II sensor is about soon I suppose.

Looking at the task (not involving compression or other things)

R6: 20x20MP=400Mpixel/s : 1/50s

R6II: 40x24MP=960Mpixel/s : If this one is 1/60s it is a big jump from R6

R5: 20x45MP=900Mpixel/s : 1/60s

More likely it is damaged/lossy compressed raw or even JPG on the Sony figures. Sony doesnt even publish FPS figures for lossless raws and they know why they hide it.

The Canons values are for lossless compressed raw.

That is the only numbers I would consider for a comparison.

Anyhow without proper source the graph doesn't have any credibility.

This is how it is, no-one will test a bunch of cameras with equal method.

I'm quite dissapointed of the wobbling ES result of R7  Duade Paton shows in his video even with multiple shots of stationary subjects.

Some part in it can be the IBIS as he stated, compensating for handheld movement at longer FL.

I'm aware of one can use mechanical shutter but that is so for every other camera aswell.

Some part in it can be the IBIS (combined with slow readoutspeed) as he stated, compensating for handheld movement at longer FL.

Are you sure about the R7? Afaik electronic shutter on R7 is still 14bit?

Do you have any source saying 14 bits?

bclaff he said in the thread "Canon R7 bit depth on electronic shutter"

this:

"

I received 3 files which is sufficient to do a quick initial test.
The files were black frames taken with mechanical, EFCS, and electronic shutters.

From the histogram I would say that electronic is 12-bit with some small amount of smoothing (I haven't done spectral analysis yet)."

No other source than Canon usually writes it in the manuals if the bit depth is lower with electronic shutter. But for R7 I haven't seen any mentions of reduced bit depth anywhere in specs or manuals...

I just checked specs on canon-europe. For R6, R6II and R5 it is specifically mentioned for all that electronic shutter is 12-bit. Look under "Still Image Type":

https://www.canon-europe.com/cameras/eos-r6/specifications/

https://www.canon-europe.com/cameras/eos-r6-mark-ii/specifications/

https://www.canon-europe.com/cameras/eos-r5/specifications/

But for R3, R7 and R10 there are no mention of reduced bit depth for electronic shutter:

https://www.canon-europe.com/cameras/eos-r3/specifications/

https://www.canon-europe.com/cameras/eos-r7/specifications/

https://www.canon-europe.com/cameras/eos-r10/specifications/

I'm not saying R7 (or R10 or R3) is 14 bit. Just asking if someone knew for a fact it is 12-bit?
